A diapir is a type of intrusion in which a more mobile and ductile material is forced into brittle overlying rocks. Diapirs can be igneous, non-igneous, or salt-related, and they can form various geological structures and trap hydrocarbons.
Diapir, (from Greek diapeirein, "to pierce"), geological structure consisting of mobile material that was forced into more brittle surrounding rocks, usually by the upward flow of material from a parent stratum. The flow may be produced by gravitational forces (heavy rocks causing underlying
The meaning of DIAPIR is an anticlinal fold in which a mobile core has broken through brittle overlying rocks.
A diapir is a relatively mobile mass that intrudes into preexisting rocks, such as salt, shale or hot magma. Diapirs can form anticlines, salt domes and other structures that trap hydrocarbons.
Astronaut photography of Jashak salt dome (the white area in the middle) in the Zagros Mountains in Bushehr province, Iran Salt dome in Fars province, Iran A salt dome is a type of structural dome formed when salt (or other evaporite minerals) intrudes into overlying rocks in a process known as diapirism. Salt domes can have unique surface and subsurface structures, and they can be discovered ...
Lávová lampa ilustruje mechanizmus výstupu diapírov. Diapír (z gr. diapeirein - prepichnúť) je geologická štruktúra, vo všeobecnosti mobilná masa, ktorá intruduje do nadložných vrstiev. Najčastejšie to sú intrúzie, ktoré prerazili cez nadložné vrstvy starších hornín, no diapír môže ozačovať aj relatívne chladné telesá (napr. soľné dómy, a bahnové diapíry ...

What is a magma diapir? 1. n. A relatively mobile mass that intrudes into preexisting rocks. Diapirs commonly intrude vertically through more dense rocks because of buoyancy forces associated with relatively low-density rock types, such as salt, shale and hot magma, which form diapirs. What determines whether a salt wall or salt diapir forms?
diapir (plural diapirs) (geology) An intrusion of a ductile rock into an overburden. quotations
Schematic diagram of a diapir rising up through the sediments. Faults that form around the diapir can lead to the development of flow systems for gas and fluids, and some of these fluids may nourish seafloor chemosynthetic communities. Pockmarks, or small depressions in the seafloor, sometimes develop above these diapirs.
